Further evidence for a global decline of the entomofauna
Abstract The Anthropocene is characterised by pervasive human‐inflicted impacts on a broad range of biota, including insects. In 2019, we reviewed scientific literature quantifying the prevalence and magnitude of insect declines in recent time. Here, drawing upon 40 additional long‐term studies, we...
